Chapter 1: Problem 5

What are the different types of database end users? Discuss the main activities of each.

Short Answer

Expert verified
The different types of database end users include Casual, Naive/ Parametric, Sophisticated, and Standalone users. Casual users often access the database infrequently and employ flexible query languages. Naive/ Parametric users use preset queries. Sophisticated users fulfill processing requirements beyond predefined queries. Lastly, Standalone users maintain personal databases using program packages.

Step by step solution

01

Identify Database End-User Types

Database end users can be divided into four types: Casual end users, Naive or Parametric end users, Sophisticated end users, and Standalone users. Each type interacts with the database in different ways and has different levels of expertise.
02

Discuss Casual End Users

Casual end users typically interact with the system infrequently, perhaps requiring different information each time they access the database. They typically rely on flexible query languages to specify requests and may require a sophisticated database interface and use some form of end-user programming language.
03

Discuss Naive or Parametric End Users

Naive or Parametric end users usually interact with the database by inputting or retrieving data from preset queries that have been programmed for them. These end users often do not need to be aware of the structure of the database, and the interface usually involves form filling on screens or menu-driven interfaces.
04

Discuss Sophisticated End Users

Sophisticated end users are those who use the database to fulfill processing requirements not met by predefined queries. This group includes scientists, engineers, business analysts, and others who perform complex queries or updates.
05

Discuss Standalone Users

Standalone users maintain personal databases by using ready-made program packages that provide easy-to-use menu-based or graphics-based interfaces.
